You people with basements don't know how good you've got it.
But hey, there's no snow here, so maybe it's not that bad! hahahahaha
Yes, 5 gallon buckets everywhere, they can be used to sit on, stand on, hold dirt, water, lizards, mice, crickets, cork bark, tools, etc. I think a nice dining set could be built from them too, but my wife strongly disagrees (women are silly).
I know the exercise program you mentioned, but IMHO it is too much work so I am trying to train children to do it for me, but they complain about the weight and just move too darn slow.... geez, kids these days...
Digging up an enclosure that the base is four foot off the ground is lots of fun too.
